SPECIFICATION forming part of Letters Patent No. 284,931, dated September 11, 1883,

Application filed May 4, 1882v (X model.) i

To all whom it may concern:

Be it known that I, WVILLIAM N. WHITE- LEY, of Springfield, county of Clarke, State of Ohio, have invented a new and useful Improvement in Reapers and Mowers, of which the following is a specification, reference being had to the accompanying drawings and letters of reference thereon, in which- Figure 1 is a perspective view of a reaper IO containing my improvements. Fig. 2 is a sectional plan of a portion of a reaper provided with differential gear-wheels having gimbalj oints to support a vibrating driving-arm and the rolling portion of the differential gear that gives it motion, with my-improvements attached thereto. Fig. 3 is an enlarged view illustrative of my improvements. Fig. 4 is a sectional plan of a portion of a machine provided with differential gear for imparting motion to the vibrating drive-arm, in which the rolling part of said gear moves on a ball-andsocket instead of a gimbal joint, and the drivearm is supported by a pivoted brace-rod; and

' Fig. 5 is an elevation of the same. Figs. 6 and 7 illustrate a modification in the manner of supporting the vibrating drive-arm.

As the object of this invention is, mainly, to simplify and perfect the machine patented to me November 13, 1877, numbered 197,192,

' 0 which may be referred to where a full description is desired, I shall confine myself to a-description of so much of it as will serve to elucidate the improvements which are the subjeet of this application.

The shaft a is cut from a tube of wroughtiron of suitable dimensions, and it is rigidly attached to the main frame 0 of the machine by means of boxes 0 and (Z. Between the boxes 0 and (Z, and rotating on shaft a, is fitted the 40 master-wheel e. The outside of the hub of the master-wheel is turned off at both ends, and on the outer end is fitted the differential gearwheel f. The wheel f revolves freely on the hub of wheel 0, and is driven by means of a 5 ratchet-wheel, g, and a pawl attached to the master-wheel. On the box (Z is secured the gimbal-ring h by means of the pins '1 and on this gimbal-ring is secured the differential wheel Z. The four pins Z form a universal joint, the intersection of the cross-axis being commen with the axis of the shaft a, which allows brass bush, p, is inserted to fit the bore thus made. The bush p is secured to the shaft to by set-screws q, and can be readily taken out for repairs, even though it should become cemented in by rust, as the void end of the hollow shaft a will furnish a convenient entrance for a drift, by which it can be driven out. It will be observed that the bush p forms a long bearing forcrankshaft -r, and thus makes it more durable, and consequently more uniformly perfect in its movements. 011 the crankshaft 1- there is fitted a fly-wheel, s, which controls the motion of the wheel Z and relieves the thrust of the knife at the time of the stroke. The knife-pitman is joined to the vibrating arm n by means of a pin, 2. The shaft a is socured to the boxes 0 and (Z by means of setscrews g, which pass through the box (Z, and. a pin, a, which passes clear through the box a and shaft a, as will be readily understood by reference to Figs. 2 and 3 of drawings.

When the machine is in operation, the master-wheel 0, through the agency of a pawl pivoted to one of its arms, communicates motion to the ratchet-wheel 9, formed upon the gearwheel f. The gearqvheelf is provided with two more teeth than the gear-wheel Z, and the gimbal-joint formed upon the shaft a by the ring it and pins Z permits the meshing teeth of the wheel Z to roll away from those of wheel f, which will then move forward two teeth. The number of teeth on wheel Z in excess of those on wheel f, and the end of the vibrating arm n being attached to the wheel Z and to the crank o of crank-shaft r, limits the wheel Z to a certain rolling motion, whichwill bring all the teeth on wheel Zsuccessively in contact with the teeth on wheel f and give to the end of arm n a vibratory movement suitable for the motion of the knife.

Should a ball-andisocket joint be used instead of a gimbal-joint, the ball may be fastened to the shaft a by means of screws 10, which ioo have their points inserted into the shell of the shaft a and their heads flush with the surface of the ball 00, so as in no way to interfere with the freedom of the shaft 1' or socket 3 and the end of the vibrating arm a may be sustained by either of the two methods shown by Figs. 4 to 7, inclusive. In Figs. 4 and 5 the arm n is shown as supported from beneath by means of a pivotal brace-rod, -A, bent at one end, so as to enter arm n in a suitable manner, and at the other end furnished with a universal joint, D, secured to a depending portion, B, of the main frame I).

the arm n is shown as suspended from. an overhanging bracket, O, by a link, F1.

Having thus described my inx ention, what I claim as new, and desire to secure by Letters Patent, isa In Figs. 6 and 7 the end t of p v "WILLIAM N. \VHIIELEY.
